Upping your own thread multiple times a day is a waste of bandwith. If you really want to use a dmm, 200hz would be fine, but setting by ear is all you need to do if you know what distortion sounds like.

well i dont really exactly know when the distortion kicks in

If you can hear, you will be able to tell when they start to distort, trust yourself. You can always use a dmm as a starting point though.

thats what i want to use so i dont have no chance of blowing them

the polk are rated for 120rms and my amp does 175rms so i dont want to over power them thats why i was gonna use a dmm to set the gains, wats a good wattage i should throw at them

175 watts would be a good start.

You have a zx850.4? What are you using the other two channels for? You can bridge it, which will give you a ton of power on tap, all of which you don't need to use, but it's nice to have headroom. In that case, set it around 250 watts.

Or 120......like they are rated?

1000hz, but really you should:

Set the gains with a dmm.
Turn them down so that they blend well with the other amps/substage.
You might want to mess with the gains some to hear what clipping sounds like. Set the gains at zero and then build up until the sound goes from a pleasant, constant tone to a flappy, ****** sound.

Or 120......like they are rated?

They are rated for 250 watts peaks, with 125 watts continuous. As you know, actual, real-world music doesn't output constant power like a sine wave. It has peaks. The ratio of peaks to average power is called crest factor. Most average music has a crest factor from 4:1 to 8:1. This means the average power will be 1/4 to 1/8 the peak power. So you'll have nice 250 watt peaks, while the average, continuous power will be closer to 50 watts.

just be careful the new momo tweets are pretty touchy. plenty of people on here with momo's looking for new tweets.

*knock on wood* had mine over a year now with 120 rms per side with no problems.

Hell, turn that **** up all the way. That fuzz sound is just the air moving.

You can still blow your speakers if you set the gains with a DMM :fyi:

If you really want your stereo to sound as good as it can, try to look past how much power you have and what you are using. The install is what will determine the potential of your components. That said, make sure you spend some time on those doors and do it right or else those Polk's are not going to meet you expectations. Fully deaden and seal the doors. As far as the baffle - you can use and MDF baffle, just make sure you treat it with some sort of sealent. There have been many cases of rotted MDF over time. Be sure that the baffle is leak free and solid. I would suggest you search some builds here and over on DIYMA to get an idea of what your door should look like. And take your time! Do not rush the install to get the components powered up... you will regret it.

well i dont have the cash at the moment to seal and deaden my doors but i will in a month or two but for now i am just gonna put them in and see how it goes

is there a cheap way to seal and deaden the doors

I'll be honest, they aren't going to sound nearly as good as they can.

There are alternatives to the more expensive deadener route, but it is worth it to wait and spend the money to do it correctly.

Yeah there's a cheap way, Peel&Seal. But after the end of the summer in Orlando, it will have melted, fallen off, or dripped tar down your doors. And then there's the smell...

No, you should just wait until you can afford a roll of RAAMmat. One roll ($120) is actually more than is needed to just do your doors, so you'll have plenty left over for the trunk (if you have a sub back there).
